Specification of Letters Patent.

Application filed A ril s, 1915. Serial No. 21,673.

Cleaning Machines, of which the followingis a specification.

This invention is an improved street cleaning machine embodying a revoluble brush for sweeping a street surface and also embodying a receptacle for the sweepings and means for loading the sweepings of the brush into the receptacle, the object of the invention being to provide an improved machine of this character which sweeps and gathers the dirt automatically, is simple in construction, is strong and durable, and which can be readily controlled.

The invention consists in the construction, combination and arrangement, of devices hereinafter described and claimed.

In the accompanying drawings;

Figure 1 is a sideelevation of a street cleaning machme constructed in accordance with my invention with the near wheel removed and the axle splndle of said wheel shown in cross section. Fig. 2 is a plan of my improved street cleaning machine. Fig. 3 is a longitudinal sectional view of the same on the plane indicated by the line a-a of Fig. 2: Fig. 4 is a detail rear elevation of the same. Fig. 5 is a detail elevation, partly in section, of the frame. 6is a detail sectional view of the'box which receives the sweepings. Fig. 7 is a detail perspective view of the arch cross bar.

In the embodiment of my invention I provide an arched rear axle 1 which is connect- 'ed by reaches 2 to the fifth wheel 3 of a front truck 1 which embodies alfront axle 5, front wheel 6, and a draft tongue 7. 4 Rear wheels 8, 9 are mounted on the spindles 10 of the arched axle 1. The wheel 8 is here shown as on the left hand side of the machine. On the inner side of said Wheel 8 is .a master gear 11 which revolves with said the front ends-of the bars 13 13 areeyes 16 which are engaged by bolts 17 whereby.

pivot connections are effected between the frame 12 and the arched axle 1 so that the Patented Mar. 28,1916.

rear end of the frame may be raised and lowered. A pair'of bearings-'17 are secured to the bars 13 13 nearthe rear ends of said bars and a cylindrical revoluble brush 18 has its shaft 19 mounted in said bearings. This brush is arranged to bear on and sweep the street surface and is revolved inthe direction indicated bythe arrow inFig. l.

The shaft 19 is provided at opposite ends with sprocket wheels 20, 21. I

A stub shaft 22 has one end mounted in a bearing 23- on the left hand bar 13 and has the other end mounted in a-bearing in an angle bracket 24 which is secured to said bar and is arranged, together with said stub shaft projecting. from the left hand side of the frame 12. A stub gear 25 is mounted for rotation on said shaft 22, engages the master gear 11, for rotation thereby, and on the inner side of said gear 25 is a clutch member 26. A sprocket wheel 27 is revolu bly mounted, is also shiftable on the stub shaft and has a clutch member '28 on one side for engagement with the clutch member 26 and is provided on the opposite side with an annularly grooved hub 29 which is engaged by a shipper lever 29*. Then the endwheels 27 and 20, so-that the revoluble brush is driven when the machine is in motion and the wheel 27 is clutched to the gear 25. To. operate the shipper lever a hand lever 32 is provided which is pivotally mounted on the arched axle as at 33, is connected to the shipper lever by a link 34 and may be locked in the desired position by means of a segment 35 and a suitable locking dog ofordinary construction operated by pinch lever 36.

A box 37, to receive the sweepings, is arranged within the-frame 12 and comprises side walls 38, a front wall 39, a hopper shaped bottom 40 and a pan 11 arranged in rear and belowthe hopper shaped bottom and connected to the fixed downwardly and forwardly inclirmd rear plate 42 of the hopper shaped bottom by a curved wall 43. The

box has its front portion arranged under the arched axle, between the vertical por tions of said axle and the side walls of the box are attached to the axle by means of angle brackets 65 which are riveted orother- Wise suitably secured to the verticalporwheels 48, 49 are on said roller. The ratchet" tions of the arched axles and also to the side walls of the box. The hopper shaped bottom also includes a member 44, which is hinged at its. front side as at 45 so that it may be lowered so as to open at the bottom to discharge a load of sweepings from the box when desired. This closure member or dump member 44. is raised and lowered by means of a roller 45 and a chain 46, the roller being mounted in bearings 47 near the front upper corners of the box. Ratchet wheel 49 is engaged by a pawl 50. A lever 51 for rotatingthe roller when desired, is pivotally mounted as at 52 and has a pawl 53 for engagement with the ratchet wheel 48. The pawl 50 is provided with a suitable treadle which may be depressed to cause the pawl to disengage the ratchet wheel 48. The.

pawl 53 may be manually disengaged from the ratchet wheel 48 to release the roller 45 and hence permit the load to be dumped from the box as will be understood. The box is provided on opposite sides, at a suitable distance from its rear end, with supporting wheels 54 which are'rnounted on stub spindles that project from opposite sides of the box. To the bottom of the pan 41 at 56 is hinged a member 56 adapted to conform with inequalities of thestreet surface. The hinged member'of the pan bottom is provided with supporting rollers 57, and also has a flexible downwardly and rearwardly inclined flange 58, which in practice may be made of rubber, leather or any other suitable material, and which bears directly on the street surface and in front of the revolving brush, so that the sweepings which are taken up by the brush are thrown forwardly therefrom onto the bottom of. the pan.

A revoluble loader 58 is arranged above the pan and comprises a shaft 59, radial arms 60 and curved blades or sweeps 61 at the outer ends of said radial arms. shaft 59 is mounted in bearings 62 in the side walls of the box and at one end of said shaft is a sprocket wheel 63 which is connected by an endless sprocket chain 64 with a sprocket wheel 21 so that said loader is driven by power transmitted thereto from the revoluble brush, and is-rotated in the same direction as the brush. The bar 13 is provided with a loop 59" to clear the shaft 59.

To raise and lower the rear end of the trailing frame as required I provide a lever 66 which is mounted as at 67 on the arched axle, as connectedby a link rod 67' to the arched cross bar 14 of said frame, and said lever is secured in adjusted position by means of a segment 68 and a suitable looking dog operated by pinch lever 36..

A seat 70 for the driver of the machine is The in the rear mounted on the arched axle. The levers 32, 5!, and 66 are in easy reach of the driver, so that he is enabled to readily control the operation of the machine. I

Having thus described my invention I claim 1. In-a street cleaning machine an ambulant frame, a trailing frame in rear of the ambulant frame, a revoluble brush mounted in the rear portion of the trailing frame, a box carried by the ambulant frame and arranged within the trailing frame, said box having a pan at its rear side arranged in front of the revoluble brush, and a revoluble loader arranged above said pan and to throw the sweepings from the pan into the box, the box being. provided with a hopper shaped bottom arranged immediately in front of the'pan and having a hinged dis- ;bear on the ground, a trailing frame aru'anged on opposite sides of the box extending rearwardly therefrom and pivotally connected at the front end to the axle, a revoluble loader having bearings in the side walls of the box, a revoluble brush arranged in rear of the pan and having bearings in the trailing frame, means to raise and lower the rear end of the trailing frame together with/ the brush, driving connections between the brush andthe loader, a stub shaft mounted on'one side of the trailing frame and having a gear engaging the main gear and also having a sprocket wheel, a second sprocket wheel on the shaft of the revoluble brush, and an endless sprocket chain connecting said sprocket wheels.

3. In a street cleaning machine, an ambulant frame and trailing frame in rear of the ambulant frame, a revoluble brush mounted ortion of the trailing frame, a box carried y the'am'bulant frame and arranged withln the trailing frame, said box having a pan at its rezfr side arranged in front of the revoluble brush and provided with a hinged rear member having supports which bear on the ground, and a revoluble loader arranged above the pan to throw the sweepings from the pan into the box.

In tes imony whereof I aflix my signature in presence of two witnesses.
